Definitions
- the present invention relates to a method for producing hydrogen from a raw material gas containing ethanol using a selectively permeable membrane reactor, and a selectively permeable membrane reactor that can be suitably used for the hydrogen producing method.
- Hydrogen is used in large quantities as a basic raw material gas for petrochemicals, and in recent years, especially in the field of fuel cells and the like, hydrogen is attracting attention as a clean energy source, and is expected to expand its use.
- Hydrogen used for such purposes is mainly composed of hydrocarbons such as methane, butane and kerosene, and oxygen-containing hydrocarbons (hydrocarbons containing oxygen atoms) such as methanol, ethanol, and dimethyl ether. It can be obtained by using a selective permeation membrane that can selectively permeate hydrogen, such as a palladium alloy membrane. It is done.
- ethanol is particularly expected as a carbon-neutral next-generation raw material because it can obtain biomass power.
- a selective permeation membrane reactor (a membrane reactor) capable of performing the above-described reaction and separation at the same time is used for the production of hydrogen (for example, see Patent Document 1).
- a selectively permeable membrane reactor generally used has a reaction tube with one end serving as a gas inlet and the other end serving as a gas outlet, and hydrogen is inserted into the reaction tube inserted into the reaction tube.
- a base material portion having a selectively permeable membrane that selectively permeates has a porous separation tube and a catalyst that promotes a reforming reaction of hydrocarbons and Z or oxygen-containing hydrocarbons.

- Such a selectively permeable membrane reactor can perform a chemical reaction using a catalyst and hydrogen separation using a selectively permeable membrane at the same time.
- the product hydrogen is permeated through the permselective membrane and removed from the reaction system, and the equilibrium of the chemical reaction moves to the production side, which enables the reaction at a lower temperature. is there.
- the specific reaction temperature is about 600 to 800 ° C for a conventional non-membrane reactor without a selectively permeable membrane, but 400 to 600 for a selectively permeable membrane reactor. About C.
- the deactivation of the catalyst due to coking is a force that occurs even in conventional non-membrane reactors.
- the main cause of coking is the hydrocarbon decomposition reaction in non-membrane reactors, but selective permeation. Since the membrane reactor is a disproportionation reaction of carbon monoxide and carbon as described above, in order to suppress the deactivation of the catalyst due to coking in the production of hydrogen using the selectively permeable membrane reactor. Therefore, a unique coking measure different from the case of using a non-membrane reactor is required.

- ethanol reforming is a reaction in which 6 mol of hydrogen is produced from 1 mol of ethanol as shown in the following formula.
- the hydrogen conversion efficiency which is an index indicating the degree of progress of this reaction, is expressed as follows, where the ethanol flow rate of the raw material is C [molZmin] and the total flow rate of hydrogen produced in the reaction is D [molZmin]. Defined.
- the total flow rate D of hydrogen generated in the reaction was A (mlZmin), which is the amount of hydrogen permeated through the permselective membrane 5 (permeated hydrogen amount) and did not permeate the permselective membrane 5.

- Comparative Example 1 is a thermodynamically caulking-shaking condition where the value of ⁇ is less than 0.6, and the amount of catalyst per unit area of the permselective membrane (volume of catalyst layer, catalyst activity) Since the values of 3 and ⁇ , which indicate the component mass, were small, the catalyst was caulked significantly. Compared with Comparative Example 1, in Comparative Examples 2 and 3, where the values of j8 and ⁇ were increased, the amount of coke deposited per unit catalyst amount decreased due to the increase in the amount of catalyst, but a coke amount of coke was deposited. did.
- Example 18 in which the value of ⁇ is 0.6 or more, it can be seen that coke precipitation is remarkably suppressed as compared with Comparative Example 13.
- the value of the diamond in Example 28 where the value of the diamond is 1.0 or more, the amount of coke deposited was near the detection limit or below the detection limit.
- coke is hardly precipitated in spite of different reaction conditions of SZC, reaction temperature, and non-permeate side pressure. Therefore, in order to suppress coking in hydrogen production using a selectively permeable membrane reactor, it was important to control the value of a to operate.
- Example 6 since Example 6 was operated under the condition that the value of a was 0.6 or more, coking was on the other hand, the hydrogen conversion efficiency and the hydrogen recovery rate were 43% and 81%, respectively, which were relatively low.
- Example 3 is a force in which parameters other than ⁇ and ⁇ are the same as Example 6. Compared to Example 6, a higher hydrogen conversion efficiency and a higher hydrogen recovery rate are obtained. From this, it is considered that in Example 6, the values of j8 and ⁇ were small and the catalyst activity was insufficient, so that the reaction did not proceed sufficiently. Similarly, when Example 7 and Example 4 having the same parameters other than j8 and ⁇ are compared, Example 4 has higher hydrogen conversion efficiency and higher hydrogen recovery rate.
- Example 7 the volume of the catalyst with a very large ⁇ value was unnecessarily large, so the distance between the catalyst located near the inner wall of the selectively permeable membrane reactor and the selectively permeable membrane was As a result, the efficiency of recovering hydrogen generated by the reaction at the permselective membrane decreases, and the decrease in the hydrogen recovery rate reduces the reaction promotion effect that is a feature of the permselective membrane reactor, thereby improving the hydrogen conversion efficiency. This is thought to have caused a decline. Further, when Example 8 and Example 3 having the same parameters other than j8 and ⁇ are compared, Example 3 has higher hydrogen conversion efficiency. This is considered to be due to insufficient catalytic activity in Example 8 because the value of ⁇ is too small.
- the values of j8 and ⁇ are large.
- the values of j8 and ⁇ are larger than necessary, the volume of the catalyst is large. As a result, it has become a component to reduce the hydrogen extraction efficiency, which in turn leads to a decrease in hydrogen conversion efficiency.
- the present invention can be suitably used for a method of producing hydrogen from a raw material gas containing ethanol using a selectively permeable membrane reactor and a selectively permeable membrane reactor used in the hydrogen producing method. is there.
